IMPLEMENT FOR CLEANING THE BORES OF GUN-BARRELS.

Specification forming part of Letters Patent No. 41,481, dated February9, 1864.

To all whom it may concern:

Be it known that I, PETER FRANCIS CARR, of Company B, 14th Regiment ofIndiana Volunteers, have invented a new and Improved Device for Cleaningthe Bores ofi Small-Arms; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this sp cification, in which-Figure lis a side View of the device. Fig. 2is a transverse section otthe same. Fig. 3 is a central longitudinal section of the same, showingit attached to the ramrod of a gun.

Similar letters of reference indicate corresponding parts in the severalfigures.

This device consists of a cylindrical plunger, which has its peripherycomposed of indiarubber or other soft elastic material coated with orhaving incorporated into it emery or other scouring or polishingmaterial, and which is fitted with ascrew and not by which it may beexpanded circumferentially to make it fitas tightly as desired into thebore of the arm, and is furnished with a screwed socket by which it isscrewed to the ramrod when the gun requires to be cleaned.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the body of the plunger, composed of a cylindrical piece ofvulcanized india-rubber coated with or having incorpo rated into it fineemery of a length of about three-quarters of an inch and of suchexternal diameter that in its normal condition it will pass freelywithin the bore of the fire-arm in which it is to be used. This cylinderhas a hole, a,right-through its center for the reception of the screw B,which passes right through it.

1 This screw has a broad=thin head, a, which l fits against one end ofthe cylinder A, and is fitted with a nut. O, which screws up against Ethe opposite end oi'the said cylinder, the said nut being so constructedas to be easily turned with the fingers. On the point of this screwthatis to say, the end farthest from the head a-there is firmly andpermanently secured a socket, D, which is screwed internally to fit thescrew 0, provided on the small end of the ramrod E of the gun, spaceenough being left between the said socket and the cylinderA to permitthe proper operation of the nut (3.

When the gun requires cleaning, the bodyA is inserted into the muzzle ofthe gun, and the nut O screwed up to compress the india-rubberlongitudinally, and thus produce its expansion circumferentially to adegree to make it fit with sufficient tightness within the bore andenter the grooves thereot. The ramrod is then screwed into the socket D,and the cleaning and polishing of the barrel is tlnn etfected by workingthe ramrod back and forth.

If pret'erred, the device may be attached to the ramrod before insertingit into the barrel.

hat 1 claim as my invention, and desire to secure by Letters Patent, is

A device for cleaning and polishing the bores of firearms, com posed ofa plunger-like body, A, of india-rubber or other elastic material,coatedwith or having incorporated into it emery or other scouring or polishingmaterial, a screw, B, nut G, and socket D, the whole combinedsubstantially as herein specified.
